General Description
The 3065 Series Antennas are based
on the original full-size broadband HF
1795 Antenna Series. The 3065
Antenna Series is more compact than
the 1765 Antenna Series for a given
low frequency cut-off. This is achieved
by frequency extension techniques
which maintain high electrical
efficiency.
Features
An omnidirectional radiation pattern
at the lower frequencies results in
improved coverage to and from base
stations over short-to-medium ranges.
The design of the radiating system has
increased the bandwidth over which
the azimuth plane pattern is
omnidirectional up to five times the
lower frequency limit and further
reduces the ground area required for
installation by 25%.
The resultant broadband antenna
configuration permits complete
compatibility with channelized as well
as frequency-agile, synthesized HF
radio systems. The antenna is also
offered in a transportable tactical
version (3065MT), which can be
installed by a crew of four in one
hour.

Characteristics
Low VSWR maximizes the power
available at the antenna, from solid
state power amplifiers, resulting in an
overall improvement in
communications reliability.
Elimination of the conventional
antenna tuning unit (ATU-Coupler),
normally required with simple narrow
band antennas, maximizes the power
available at the antenna, resulting in
an overall improvement in
communications reliability. In
addition, there is a reduction of
maintenance/control complexity
associated with an ATU-Coupler.
High Take-Off Angle
The elevation plan radiation patterns
at the lower frequencies ensure
maximum power is radiated at high
angles, providing reliable
communications over short-to-
medium ranges.
Accessories
The following accessories are available
for ease of installation and
maintenance: tower lighting kit,
erection kit, paint kit, tool kit,
lightning rod kit, anti-climbing kit, and
spares kit.
